School increases IQ

Dyscalculia: News from the web:

Where many people believe that your IQ is pretty much set in stone, a new analysis shows that after a year of school, children’s IQ gets a boost.

A year of schooling leaves students with new knowledge, and it also equates with a small but noticeable increase to students’ IQ, according to a systematic meta-analysis published in Psychological Science, a journal of the Association for Psychological Science.

“Our analyses provide the strongest evidence yet that education raises intelligence test scores,” says psychological scientist Stuart J. Ritchie of the University of Edinburgh. “We looked at 42 datasets using several different research designs and found that, overall, adding an extra year of schooling in this way improved people’s IQ scores by between 1 and 5 points.”

How to spot dyscalculia in early childhood

Dyscalculia: News from the web:

Researchers seem to have found the place where to look for dyscalculia, here is their abstract:

Mathematical learning deficits are defined as a neurodevelopmental disorder (dyscalculia) in the International Classification of Diseases. It is not known, however, how such deficits emerge in the course of early brain development. Here, we conducted functional and structural magnetic resonance imaging (MRI) experiments in 3- to 6-year-old children without formal mathematical learning experience. We followed this sample until the age of 7 to 9 years, identified individuals who developed deficits, and matched them to a typically developing control group using comprehensive behavioral assessments. Multivariate pattern classification distinguished future cases from controls with up to 87% accuracy based on the regional functional activity of the right posterior parietal cortex (PPC), the network-level functional activity of the right dorsolateral prefrontal cortex (DLPFC), and the effective functional and structural connectivity of these regions. Our results indicate that mathematical learning deficits originate from atypical development of a frontoparietal network that is already detectable in early childhood.

Check for understanding

Dyscalculia: News from the web:

Teaching is a two way street. You can be the best teacher ever but if your brilliant messages are not understood by your audience, you will not get the results you were aiming for.

simply asking ‘have you understood?’ This tells us almost nothing – as students rarely so no or could be wrong in saying yes. But, most importantly, there are always degrees of understanding. Instead of asking if, we should ask what student have understood. Rosenshine gives us a nice list of ways teachers can check for understanding.:

Visual math

Dyscalculia: News from the web:

New research is presented on the page from Stanford by youcubed from Jo Boaler and it all shows how visual math can be.

our brain wants to think visually about maths. Building students’ mathematical understanding doesn’t just mean strengthening one area of the brain that is involved with abstract numbers, it means strengthening connections between areas of the brain and strengthening the visual pathways.
